LaViolette has been on the witness stand for the past nine days and has testified that Arias, 32, was a victim of domestic violence. Arias says she shot and repeatedly stabbed former boyfriend Travis Alexander in June 2008 at his suburban Phoenix home. Arias says Alexander, 30, attacked her and she was forced to fight for her life.

Martinez used text messages in Alexander's own words to attempt to portray Arias in a negative light. In one message, Alexander told Arias she was "evil."

"And then it ends it by saying, 'You are the worst thing that ever happened to me,' correct?" Martinez said.
